"Great service all around from Bob Jensen. Free in home estimate with no pressure sales tactics. When it came to the installation, it was nice to know that they use their own crew, they do not subcontract out the work, so you know what you're going to get. On the day of installation, the sales person came also to ensure that we all understood what was going to happen. The install technicians, Tony and Sammy, took time to ensure that everything was done correctly and answered all the questions I had. I would highly recommend this company for any of your HVAC needs."

"We hired Airmercia Air Conditioning & Heating to evaluate our heating system and propose repair solution. Ryan was very professional and punctual. He did not make any force sales. He just offered various repair and replacement solutions and explained pros and cons for each one. We decided to replace our furnace and duct system. Ryan did an excellent Job!! I highly recommend him for your HVAC project."

"They were actually a second opinion for my non-working air conditioner but I went with them because they were very thorough and cheaper then the first company that looked at it. They replaced the same part as the first company quoted but were about $400 cheaper. They also managed to get the part in 2 business days where the other company said over a week. I didn't sacrifice cost for service though, they did a great job and now my AC works better than ever. I would definitely use them again. Another added bonus was that the repairman was a Air Force reservist and I am happy to support our troops and happy to support a company that also supports our troops.

"I was really impressed with the service provided by Nadav and he is team. I have a thirty year old home that still had the original HVAC systems. One located in the attic and the other underneath the house. Neither of these installations was simple. The Sky Clean Air team quoted me two days to remove and install new systems. The install crew was really professional, courteous and hard working. The underneath the house install was especially difficult with a tight crawl space in a less than hospital environment. These guys were not a show up at 10 leave at 3 pm crew.......they worked long hours both days to ensure they met the promised schedule.They kept me informed any issues throughout the installation process so there were no surprises. At the end of two days we had two beautifully installed systems that now cool our 4000 sq ft house in a matter of an hour instead of the 4 or 5 the old system required. I feel that the pricing they gave me was very fair and at the end of the job I felt like I got more value than what I paid. I would certainly use them again in the future."

"My ac, heater, and thermostat all went out at the same time. I called an hvac company and they said I needed a new furnace and ac and it'd be $12k. I called Heating and Air 365 to try to get a cheaper quote on a new system. Tommy came out and said the system was fine. It just had a short in the thermostat wires by the ac, my dog must have chewed through them. He replaced the wires and fixed something in the furnace and everything is working great. He saved me thousands. It's refreshing to see some honesty out there. He's got my business for life."

Heating and Air Conditioning questions, answered by experts

The best time of year to purchase or replace an HVAC system, including components like an air conditioner or furnace, is during the off-season—spring and fall. During these periods, HVAC professionals are less busy than in summer and winter, when extreme temperatures create urgent demand. Shopping during the off-season can lead to savings of 10% to 15% on an AC unit and allows you more time to find the best deal and other cost-saving incentives. Typically, air conditioning units go on sale in the fall after demand drops, while furnace prices tend to decrease in the spring.

Freon will go in the refrigerant lines near the back of your AC unit. Look for small ports with caps on a thin copper line—the Freon goes into those ports. You are best off hiring a licensed HVAC professional who can complete the job safely and correctly.

Yes, ventless portable air conditioners exist, and not all standard portable air conditioners must be vented through a window.

Ventless portable units, often called evaporative coolers, do not have exhaust hoses. They use a water reservoir and a cooling pad to add moisture to the air, making it feel cooler. These units work best in dry climates because humid areas cannot absorb much additional moisture.

For standard portable air conditioners that do require venting, a window is not the only option; they can also be vented through a door, wall, or ceiling. However, it is essential to vent these units properly. Running a standard portable AC without venting it is counterproductive because it needs to expel heat to cool the room. Failing to do so will only increase the room's temperature.

There are several common types of HVAC systems that you may have, including split systems, hybrid HVAC, duct-free systems, packaged heating and air, geothermal heating, or even portable units for heating or cooling. If you aren’t sure which type is in your home or are looking to install something different, you should consult an HVAC pro to determine which option is right for your heating and cooling needs.

A new HVAC system combines components to control indoor temperature and air quality. Features include a furnace or heat pump and an air conditioner or evaporator coil, depending on the climate requirements. It also involves a network of ductwork for air distribution, a thermostat for temperature regulation, and electrical connections. Air purifiers or humidifiers can be integrated to improve indoor air quality.
